WHEELBAR'ROW-WHEEL.

SPECIFICATION forming part of Letters Patent No. 305,313, datedSeptember 16, 1884-.

Application filed March 3, 1884. (No modoLi .the same, reference beinghad to the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in wheels,its object being to provide a wheel for such vehicles as 'wheelbarrows,harvesters, and the like, in

which the hub extends equally on each side of the spokes and fellies;and it consists in providing a wheel of this class with a hub which ismade up of two parts, which are similarly constructed and provided withflanges, which form recesses for the ends of the spokes adjacent to thehub, said plates being adapted to be secured to each other by boltswhich pass through each alternate spoke, said metallic hub beingprovided with oil-cavities, as will be hereinafter more fully set forth.

My invention further consists in the improved method of constructing andmanufacturing the wheel, whereby the cost'of the same is'reduced.

In the accompanying drawings, Figure lis a side view showing one of thehub-plates removed, and a portion of the felly in sections, the originalperiphery of the wheel being shown in dotted lines. Fig. 2 is averticalsection. Figs. 3 and 4 are detailed views, and Fig. 5 is an enlargedsectional view taken through the center portion of the wheel.

A A represent the hubs, which are provided with lateral sideextensions,a a, which are provided with a longitudinal perforation, asshown, for the reception of the spindle, a portion, as shown at 1;,being enlarged, so as to provide an oil-cavity, in which oil maybeinjected through the perforation b. At the end of the bearing, andbeyond the vertical side of the portion of the hub-plate which embracesthe ends of the spokes, is provided a continuous projecting portion, a,which forms a bearing for the ends of the spokes when they are placed inthe hub. The side pieces, A', which embrace the sides of the spokes, areprovided with projecting portions B, which radiate from the center.These projecting portions B taper from the outer periphery of the hubtoward the center adjacent to the inwardlyprojecting flange 0, adjacentto which they are beveled, as shown. These projecting portions B formsockets for the tapered ends of the spokes, and, if desirable, theseportions B may have circumferential lugs formed on each side of thesame, as indicated by the let ter B, in which case the spokes will beprovided with corresponding recesses, into which the aforesaid lugs willfit.

When it is desired to secure the parts of the wheel together, the endsof the spokes, which are tapered, as shown in Figs. 1 and 5, are placedwithin the sockets, and bolts are passed through the perforations in theplate, and through four or more of the spokes,which are provided withperforations for the reception 5 of the same, and the parts are securelyclamped upon each other. It will be readily seen that the ends of thespokes will be securely clamped between the parts of the hub in a rigidmanher, and as each side of the hub is identical in construction, butone mold and set of tools for finishing the same is required. In formingthis casting by providing the oil-cavities b, I not only provide a meansfor lubricating the spindle, but also dispense with boring out or truingthat portion of the bearing.

The spokes of my improved wheel, as indicated by the letter O, are ofordinary construction-that is to say, they are cut so as to berectangular in cross-sections, the thickness of the same correspondingwith the width of the felly, and their ends are tapered adjacent to thehub-section and provided at their outer ends with a projecting portionand shoulders. The tapered ends of these spokes are, however, providedwith a recess, 0, forthe reception of the lugs B upon the hub-plateswhen such lugs are used.

The fellies B are made from strips of lumber of the proper width andthickness, which 100 straight strips of lumber are alternately cut atopposing angles, after which the ends are dressed, so as to provide thetongue and groove portion E E, each of these sections being in the shapeshown in Fig. 1 in dotted lines. These tongue and groove ends of thesections '13 are adapted to fit within each other, and,

when placed together, will form an octagonal rim, the points of contactbetween the sections converging toward the center of the hub. Thecentral portion of each of these sections is provided withspoke-sockets, as shown.

lVhen it is desired to place the rim upon the wheel, the felly-section Dmay be first secured to the spokes and the same placed in position inthe hub; or the spokes may be secured to the hub first, and thefelly-section placed thereon afterward. After the wheel has been puttogether, as will be fully understood by reference to Fig. 1 of theaccompanying drawings, the corners are removed and the felly cut away,so as to form a true circle, after which itis ready for the reception ofthe tire.

If desirable, the sectional pieces of the felly D, which are all of thesame size and identical in construction, may be sawed into the propershape by a suitably-constructed implement, or the rim may be sawed afterit is placed in position by a cylindrical saw.

It will be seen that by the construction hereinbefore described andillustrated in'the accompanying drawings, as the parts of the wheel areidentical in construction, they will match, and the separate parts ofthe wheel may be manufactured separately in quantities; and by providinga felly with grooved meeting surfaces which match into each other,lateral displacement will be prevented and the wheel rendered moresolid.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a wheelbarrow-wheel, a hub composed of two separate and identicalsections, A A, provided, "respectively, with inwardlypro jectingportions B and a central projecting flange, 0, and a continuousperforation forming a spindle bearing bolts for clamping the parts toeach other and upon the spoke, substantially as shown, and for thepurpose set forth.

2. The" improved hub for wheelbarrowwheels, provided with a longitudinalspindlebearing, a, having oil-cavities b, and side bearing-plate, A,with projecting portion B, and a central flange, 0, said plate beingprovided with perforations for the reception of clamping-bolts,substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
